Soil Process - Soil Contains Carbon


Soil is unique resource that most every living thing (above deep water sources) relies on it for survival. Just like water is key part of life. In the plant life, and health of atmosphere, Carbon intake is important and the plants absorb Carbon and releases oxygen.  Soil is a dynamic, living system that has sum of carbon (C), which is an important regulator of the global carbon foot print. Geological location on the planet, with climate and vegetation will influence the Carbon (C) storage as will topography. Uplands can have a low amount of Carbon (C) then low lands. In wet and hot climates increasing decomposing increase the Carbon (C) in soil bank compared to dry and hot or cold that . Soil faunas, roots, fungi, and microbes interact with mineral and organic material to process the soil Carbon (C). Soil gasses are temperature sensitive and with global warming occurring could release more C into the atmosphere. Carbon loss in soil can also occur in erosion and leaching were dissolved carbon can be present in groundwater. Carbon (C) storage can also be influence by the soil texture which is based on particle size. Carbon in the soil is used by plants along with CO2 in the atmosphere and in the respiration oxygen is release. Many plant species form a reliance with certain fungi in the soil by producing  energy from their roots, like carbon (C), and in return the fungi provides the plant with nutrients like phosphorus..
